Be it known that I, WALLACE A. DUNTON, a citizen of the United States, residing in the city. of and county of Los Angeles, State of California, have invented a new and useful Intra-Uterine irrigator, of which the following is a specification.

My invention relates to improvements in' uterus any eft'ete or injurious matter, such as pieces o f'the placenta, blood'clots, &c.,' and, fourth, to provide an irrigator that may be easilyinserted in and removed from the uterus and which may be easily cleaned. I attain these objects by the mechanism described herein and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my irrigator. Fig. 2 isa longitudinal section of my irrigator. Fig. 3 is an elevation of that part of 'the irrigator showing specially the slit in theouter Fig. lis a cross-section on the line 4 4 of Fig. 1, and Fig. 5 is an end view ofmy irrigator from the pointed end thereof.

A is the shell or body portion of the irrigator, conical in shape, with a longitudinal slit B therein extending from end to end, as shown in Fig. 3. The irrigator is made conical that it may be easily inserted into the uterus, and being open at the large end the light is permitted to enter, lighting up the interior of the irrigator and that portion of the uterus projecting into and along the slit B, thereby affording ready access to the interior of the uterus for treatment.

Removably affixed within the shell A is the supply-tube D for conveying water from any convenient supply to the discharge end of the tube for washing out the uterus. This tube is located as far in the shell A as the opening in the shell will permit-that is, untilthouter edges of the end engage with, the inner walls to inspect all parts of the uterus.

of the shell-A. It is held firmly in this position by the spring-catch F. The tube D is removably affixed, that it may be readily removed for cleaning.

In theinner end of the tube D and running thence along the side next to the slit B and registering therewith is a longitudinal slot E, through which the water to clean the uterus passes.

The outflow-passage gradually increases in size, thereby affording less obstruction to the outflow, and should any clotted blood or pieces of placenta lodge therein it is only necessary to gently move the instrument forward and back inthe uterus and the obstructing de-' tritus coming in contact with the walls of the uterus through the slit in the shell is dislodged and passes out.

My instrument is easily rotated while in the uterus, and its conical shape enables the operator through the slit in the side thereof Should there be any small pieces of the placenta or other removable matter clinging to the walls of the uterus, the rotation of my irrigator has a tendency to cause the same to be detached therefrom. WVith curved irrigators such as are now in common use this cannot be done, as the curvature is too great to permit of their rotation in the uterus.

conical shell terminating in an inner rounded 7 point and having a slit extending from the inner rounded point to the rear or open end; a water-supply tube attached to and within said shell, the outer end thereof provided with means for attachment to a water-supply, the inner end terminating near the point of the outer shell and having a longitudinal disply; and having a longitudinal slot in the inspring-catch F for holding the supply-tube in ner end, as and for the purposes shown and place in said shell, substantially as and for described. the purpose shown and described.
